应用ＥＬＩＳＡ检测了正常人和肺结核患者的血清可溶性白细胞介素２受体（ｓＩＬ－２Ｒ）和抗ＰＰＤ抗体水平。结果表明，活动性肺结核患者的血清ｓＩＬ－２Ｒ和抗ＰＰＤ抗体呈正相关（γ＝０．４３３，Ｐ＜０．００１），而且两者的水平明显高于正常对照组；抗ＰＰＤ抗体阳性的活动性肺结核患者血清中ｓＩＬ－２Ｒ浓度明显高于抗体阴性患者，提示血清ｓＩＬ－２Ｒ浓度测定可以反映肺结核患者细胞免疫功能状态。 Serum levels of soluble interleukin 2 receptor (sIL-2R) and anti-PPD antibodies were measured by ELISA in normal and tuberculosis patients. The results showed that there was a positive correlation between serum sIL-2R and anti-PPD antibodies in patients with active pulmonary tuberculosis (γ = 0.433, P <0.001), and the levels of both were significantly higher than those of the normal control group The serum concentration of sIL-2R in patients with tuberculosis was significantly higher than that in patients with negative antibody, suggesting that serum sIL-2R concentration could reflect the cellular immune function of patients with pulmonary tuberculosis.
